Topic: Equalisation Yes or No

I've been digitising my LP, Singles and Cassette collection for some years now. With Brian Davies's ClickRepair suite of filters I get excellent results. Having been given a Shure M78S cartridge for Christmas I have started digitising my collection of 78s which has sat in the loft for the past 30+ years untouched. Again the results I've been getting are impressive.
However, the one thing that baffles me is the issue of equalisation - applying an inverted RIAA curve followed by EQ for the particular brand of 78 I'm converting. I fully understand the concept. However whenever I apply the curves the end result sounds very tinny. The high frequencies seem vastly magnified and even the slightest distortion accentuated to the point that it is not enjoyable to listen to. Applying furhter low end EQ and a low pass filter to compensate just seems to result in a sound quality not dissimilar to what I started with before introducing all the EQ.
Is this others experience also? Or am I missing something?
My setup is a Shure M78S cartridge, Garrard 401 turntable, SME 3009 S2 arm, Yamaha A-S500 amp and Apple iMac using Audacity.
